I saw the Polks at crutchfield and they have got some good reviews. I also heard good things about the Pioneer Revs. Which sound better for the price.

Polk: 59.99
Pioneer: 72.55

Please keep price in consideration. Is the sound quality worth the extra $12?

I need better speakers than my Sony xplods and I am considering either the Polks or Pioneers. I have a 75 X 4 channel amp and NO SUB, so I am basically looking for one which have more bass. I realize they are only 6.5" but the differences?
